This study aimed to investigate CPP in HH patients and compare clinical features between before and after gonadotropin-releasing hormone (GnRH) agonist treatment. A total of 30 HH patients under 18 years of age who visited Severance Children\u2019s Hospital between January 2005 and May 2020 were retrospectively reviewed. Fourteen patients were male (46.7%) and sixteen (53.3%) were female, with a mean age at diagnosis was4.2 \u00b1 2.9 years. During follow-up, 24 patients (80.0%) were diagnosed with CPP, 15 patients (50.0%) had gelastic seizure, and 13 patients (43.3%) had developmental delay. The gelastic seizure was significantly associated with sessile type HH rather than pedunculated type HH (85.7% vs. 18.8%, p = 0.001). After GnRH agonist treatment, discrepancies between bone age and chronological age decreased (3.3 \u00b1 1.3 years to 2.0 \u00b1 1.7 years, p = 0.002). Additionally, height standard deviation score for bone age was increased, and predicted adult height increased significantly in females, while males showed an increasing trend. Clinical symptoms of HH were closely associated with the location of HH, and GnRH agonist treatment was safe and effective in the management of CPP caused by HH.<\/jats:p>","DOI":"10.3390\/children8080711","type":"journal-article","created":{"date-parts":[[2021,8,18]],"date-time":"2021-08-18T10:54:35Z","timestamp":1629284075000},"page":"711","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Management of Central Precocious Puberty in Children with Hypothalamic Hamartoma"],"prefix":"10.3390","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2092-2585","authenticated-orcid":false,"given":"Junghwan","family":"Suh","sequence":"first","affiliation":[{"name":"Department of Pediatrics, Severance Children\u2019s Hospital, Endocrine Research Institute, Yonsei University College of Medicine, Seoul 03722, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Youngha","family":"Choi","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Severance Children\u2019s Hospital, Endocrine Research Institute, Yonsei University College of Medicine, Seoul 03722, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jun Suk","family":"Oh","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Severance Children\u2019s Hospital, Endocrine Research Institute, Yonsei University College of Medicine, Seoul 03722, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8497-5934","authenticated-orcid":false,"given":"Kyungchul","family":"Song","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Severance Children\u2019s Hospital, Endocrine Research Institute, Yonsei University College of Medicine, Seoul 03722, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Han Saem","family":"Choi","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Severance Children\u2019s Hospital, Endocrine Research Institute, Yonsei University College of Medicine, Seoul 03722, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9692-2135","authenticated-orcid":false,"given":"Ahreum","family":"Kwon","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Severance Children\u2019s Hospital, Endocrine Research Institute, Yonsei University College of Medicine, Seoul 03722, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5016-8539","authenticated-orcid":false,"given":"Hyun Wook","family":"Chae","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Severance Children\u2019s Hospital, Endocrine Research Institute, Yonsei University College of Medicine, Seoul 03722, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1135-099X","authenticated-orcid":false,"given":"Ho-Seong","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Severance Children\u2019s Hospital, Endocrine Research Institute, Yonsei University College of Medicine, Seoul 03722, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,8,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"131","DOI":"10.1097\/nen.0b013e3180302090","article-title":"The histopathology of hypothalamic hamartomas: Study of 57 cases","volume":"66","author":"Coons","year":"2007","journal-title":"J.
